Service Intent must be explicit的解决方案

今天在学习AIDL的时候,通过以下步骤:

在AndroidMenifest中声明service


    <service
        android:name=".MyService"
        android:process=":remote"
        android:exported="true">
        <intent-filter >
            <category android:name="android.intent.category.DEFAULT"></category>
            <action android:name="com.ihealth.learnaidl.MyService"></action>
        </intent-filter>
    </service>

在客户端中绑定service


Intent intentService=new Intent();
                intentService.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
                intentService.setAction(ACTION_BIND_SERVICE);
                MainActivity.this.bindService(intentService,mServiceConnection,BIND_AUTO_CREATE);

运行程序,结果报错了!
java.lang.IllegalArgumentException: Service Intent must be explicit

这里写图片描述
经过查找资料Stackoverflow.com,发现是需要将隐含意图转换为显示的意图，然后启动再服务。

所以综合Stackoverflow上给出的解决方案,现在大体上有两种解决的方法.

1.先说一个简单的办法

Intent mIntent = new Intent();
//自定义的Service的action
mIntent.setAction("XXX.XXX.XXX");
//自定义Service的包名
mIntent.setPackage(getPackageName());
context.startService(mIntent);

即只需要多加一句话mIntent.setPackage(getPackageName());就可以解决.

2.另外一个比较麻烦的方法
先通过一个函数将隐式调用转变为显示调用

/*** 
     * Android L (lollipop, API 21) introduced a new problem when trying to invoke implicit intent, 
     * "java.lang.IllegalArgumentException: Service Intent must be explicit" 
     * 
     * If you are using an implicit intent, and know only 1 target would answer this intent, 
     * This method will help you turn the implicit intent into the explicit form. 
     * 
     * Inspired from SO answer: http://stackoverflow.com/a/26318757/1446466 
     * @param context 
     * @param implicitIntent - The original implicit intent 
     * @return Explicit Intent created from the implicit original intent 
     */  
    public static Intent createExplicitFromImplicitIntent(Context context, Intent implicitIntent) {  
        // Retrieve all services that can match the given intent  
        PackageManager pm = context.getPackageManager();  
        List<ResolveInfo> resolveInfo = pm.queryIntentServices(implicitIntent, 0);  

        // Make sure only one match was found  
        if (resolveInfo == null || resolveInfo.size() != 1) {  
            return null;  
        }  

        // Get component info and create ComponentName  
        ResolveInfo serviceInfo = resolveInfo.get(0);  
        String packageName = serviceInfo.serviceInfo.packageName;  
        String className = serviceInfo.serviceInfo.name;  
        ComponentName component = new ComponentName(packageName, className);  

        // Create a new intent. Use the old one for extras and such reuse  
        Intent explicitIntent = new Intent(implicitIntent);  

        // Set the component to be explicit  
        explicitIntent.setComponent(component);  

        return explicitIntent;  
    }

然后调用

Intent intent = new Intent();
                intent.setAction(ACTION_BIND_SERVICE);
                final Intent eintent = new Intent(createExplicitFromImplicitIntent(this,intent));
                bindService(eintent,mServiceConnection, Service.BIND_AUTO_CREATE);

两种办法都可以解决.记下来,免得以后忘了.
